KAPTON Kapton,POLYIMIDE FILM,Polyimide Film

KYPICR/KYPIFCR

Properties
Polyimide CR Film(KYPICR) is Polyimide corona-resistant film which has high corona-resistant and heat-conductive property, high& low temp and radiation resistant, excellent electrical properties, good dimensional stability and self-adhesive ability as well. It can work in the temperature -80~+260c(-112~500F) for a long time. It can be widely applied for winding insulation of magnet wires for C class traction motors , high-voltage motors and generators etc.

Polyimide FCR Film(KYPIFCR) is Polyimide corona-resistant film coated with FEP resin on one side(FH) through the sintering process at high temperature, which combines the excellent properties of Polyimide corona-resistant film and FEP resin. It can be widely applied for winding insulation of magnet wires for H~C class traction motors , high-voltage motors and generators etc.
